I am about to test migrating my Ubuntu installation to 64bit. I’ll test compatibility with my used applications first in a VM.

For that I installed Ubuntu 8.10 64bit Desktop edition into the VM. Since I don’t want to manually reinstall all packages by hand, I came up with the following aptitude / dpkg commands after reading a few other instructions:

On the source system, execute:

sudoaptitude search '~i !~M'-F'%p install'> packages-list

This will generate a list of all manually installed packages in packages-list. (All packages not installed as a dependency of another package.)

My Vinagre VNC backport for Gutsy will make it into the official gutsy-backports repository if I get two successful test reports on bug #191077. So please download and test, if you are interested.

Also, I have the beta version of the upcoming 1.10 release of the Transmission Bittorrent Client in my PPA. I use the same packaging as the official Ubuntu versions. (As opposed to the ones you’ll get at getdeb.net)
